This specification provides a system for specifying significant properties of commonly used polyurethane foams. This specification applies to slab, bonded, and molded flexible cellular products. Urethane foam may be generally defined as an expanded cellular product produced by the interaction of active hydrogen compounds, water and isocyanates. This standard does not apply to foam made from vinyl chloride and polyolefin polymers. For specifying vinyl chloride foams use ASTM D1565, Specification for Flexible Cellular Materials Vinyl Chloride Polymers and Co-Polymers - Open Cell Foam, or ASTM D1667, Specification for Flexible Cellular Materials Vinyl Chloride Polymers and Co-Polymers - Closed Cell Foam. For specifying polyolefin foams, like polyethylene foams, use GMW15063, Polyolefin Foams Non-crosslinked and Cross-linked for General Applications.

Material Description. This specification covers two types of flexible urethane foam based on application.

• Type I: Non-acoustical applications.

• Type II: Acoustical applications. Not specified by GMW14196.

Typical Applications. The foam approved for this specification is to be used for general applications in the interior of the vehicle.
